BOTTLE-SEAL.

SPECIFICATION forming part of Letters Patent No. 730,812, dated June 9, 1903. Application filed July '7, 1902. Serial Noll4,665. (No model.)

a citizen of the United States, residing at Bal-.

timore city, in the State of Maryland, have invented new and useful Improvements in Bottle-Seals, of which the following is a specification.

My invention relates to bottle-seals; and its object is to provide a device of the character named which will be so constructed and applied to the bottle-neck as to insure a her metic sealing of the bottle, but permit of the ready removal of the cap or seal by the aid of a suitable opener.

The invention consists of a cap comprising a disk, a depending annular flange, and a packing below the disk, in combination with a bottle-neck formed with an external annular groove, into which a portion of the metal of the depending flange is compressed.

The invention also consists of a cap comprising a disk, a depending annular flange, and a packing below the disk, in combination with a bottle-neck formed with an eX- ternal annular groove into which a portion of the metal of the depending flange is compressed, the lower edge of said depending flange being formed with an annular bead or reinforcement adapted to be engaged by an opener.

In the drawings, Figure 1 is a vertical section of the sealing-cap asit appears before application to the bottle-neck. Fig. 2 is a similar view of the cap applied to a bottleneck.-- Fig. 3 is a vertical section of a modified construction of the sealing-cap, and Fig. 4 is a similar view showing the modified form of cap applied to a bottle-neck.

The reference-numeral 1 designates a bottle-neck formed adjacent to its upper end with an annulargroove 2, which forms an annular shoulder 3. The bottle-neck .is also preferably formed with an annular shoulder at below the groove 2 for the purpose hereinafter described.

The cap or seal consists of a disk 5 and a depending annular flange 6, and within said flange, immediately below the disk 5, is located a packing 7, of cork or other suitable material.

The construction of sealing-cap shown in Fig. 3 is similar to that illustrated in Fig. 1,

except that the lower edge of the flange 6 is turned upward to form a reinforcing-bead 8.

The manner of applying the seal to a bottleneck is clearly shown in Figs. 2 and 4. After the cap is placed over the bottle-mouth the flange 6 is compressed by any suitable mechanism to form an inwardly-projecting annular shoulder 9, which enters the groove 2 of the bottle-neck and engages below the shoulder 3 to securely retain the cap in position. This annular inwardly-projecting shoulder 9 is formed at about the vertical center of the flange 6, and that portion of said flange extending below the shoulder 9 closely embraces the bottle-neck below the groove 2 therein. The lower portion of the flange 6 engages a smooth surface of the bottle-neck, and the lower edge of said flange afiords a convenient and reliable extension for the engagement of the ordinary opener in removing the cap from the bottle. 7

The lower edge of the flange 6 of the cap is protected by the annular shoulder 4 on the bottle-neck.

The annular bead 8 aifordsa strong and reliable grasping surface for an opener, and

for this purpose, as well as for the purpose of reinforcing the flange, constitutes a feature of utility.

It will be obvious from the foregoing de scription' in connection with the illustration in Figs. 2 andwl of the drawings that the inward compression of the flange of the cap firmly secures the cap in position and forces the packing into firm and secure contact with the top edge of the bottle-neck. When the cap is secured to the bottle, the annular shoulder 9 and the depending portion of the flange below said shoulder closely embrace the bottle-neck and make a secure stopper and one which may easily be removed by the ordinary devices for this purpose.

I claim 1. The combination with a bottle neck formed with an external annular groove near its upper end, and a smooth portion below said groove, of a sealing-cap comprising a disk, a packing below the disk and an annu lar depending flange compressed at about the center of its height to form an inwardly-extending shoulder fitting the groove in the bottle-neck, and a depending portion below the shoulder to embrace the bottle-neck, the ing portion below the shoulder "to embrace lower edge of said depending portion affording the bottle-neck, the lower edge of said flange means for engagement of an ordinary opener. being formed with an annular bead, to aiford 2.
